Title: Improvements in and relating to safety razors
IPC: B26B21/32
Filed: 1933-12-12
Abstract: 430,030. Safety razors. GILLETTE SAFETY RAZOR CO., 15, West 1st Street, Boston, U.S.A. Dec. 12, 1933, No. 34973. Convention date, Aug. 2. [Class 30] A safety razor of the clamped blade type has means whereby cap sections 44 can be folded inwardly from opposite sides of the guard 10 to meet over the flexible blade 60 or its supporting surface on the guard and then moved as a unit towards the guard in a direction perpendicular thereto to clamp the blade, a reverse operation of the said means serving to unclamp and then uncover the blade. The cap sections 44 have lateral arms 46 pivoted at 48 to transverse end bars 42 of a carrier also comprising integral L- shaped parts 38 passing through notches in the guard and joining the bars 42 to a raised crossbar 36 which locates the blade 60 transversely in the clamped position and engages a slot 20 in the guard 10. Cams 50 on the arms 46, coaxial with the pivots 48, are engaged by pins 52 in notches in the guard through which the arms 46 pass, after the carrier and the contiguous cap sections 44 have been raised by a rod 30 operated by a nut 26 forming part of the handle. The rod 30 is united to the crossbar 36 and keyed to the head 22. The pins 52 cause the cap sections to pivot apart and finally rest on grooves on the guard teeth. During this stage, the bars 42 raise the blade 60 from the guard so that it may easily be replaced or removed for cleaning. The blade has the usual slot with enlargements which enable pins 58 on the guard to locate it longitudinally. The end guard teeth may have outwardly widened parts which act as stops for the cap sections and also as fulcra enabling the sections to be brought together again when the carrier is screwed down.

Abstract: 449,142. Lathes. PITTLER WERKZEUGMASCHINENFABRIK AKT. - GES., Wahren, Leipsic, Germany. Dec. 19, 1935, No. 35243. Convention date, March 2. [Class 83 (iii)] An electrically-operated turret lathe has the speed of the driving motor controlled by switch-operated mechanism through adjustable cams carried on the machine bed and controlled by the indexing movement of the turret. The reciprocating turret slide 25 carries a tool turret 5 which may be indexed from a handwheel 1 through gears 3, 4. The gear ring 4 drives a control shaft 7 carrying a long gear 8 engaging one of the wheels 9, 9<a> on a shaft 10 geared at 11 to a shaft 13 which rotates at the same angular speed as the turret head. The shaft 13 carries a double clutch member 14 and loose control discs 15 ... 18 which are clamped up after angular adjustment to lock them to the member 14. Each control disc carries one or more cam recesses 20 coacting with a lever to operate a switch 24 controlling the speed of the driving motor so as to give three forward speeds and one reverse speed for this motor. A bar 26 on the turret slide carries a cam 27 which may coact with a roller 28 on a lever operating a reversing switch 31 which is interconnected with a further device whereby the reversal is only effective if an operation such as thread cutting is being effected. When indexing is effected the shaft 13 is rotated to change the motor speed in accordance with the next tooling operation, and, if required, the cam 27 acts at the end of the forward turret slide travel to reverse the direction of the work W.

Title: Improvements in or relating to processes for the manufacture of magnesium or alloys thereof
IPC: C22B26/22
Filed: 1935-12-23
Abstract: Magnesium nitride is obtained by passing nitrogen through a mixture of a magnesium compound such as oxide and a carbonaceous reducing agent at a high temperature, which may be about 1500 DEG  C., in an atmosphere free from moisture.ALSO:Magnesium is obtained by heating magnesium nitride to a temperature, for example about 1600 DEG  C., sufficiently high to decompose it into magnesium and nitrogen, in the presence of a substance, which may be a calcium compound such as calcium carbide or silicide, which combines with the nitrogen and prevents its recombination with magnesium.  Fluxes such as fluorides may be present.  The magnesium may be distilled off at normal or reduced pressure in a current of inert gas, or alternatively in a large excess of hydrogen, and may be collected in vacuo or in an inert gas, or it may be combined directly with other metals such as aluminium or beryllium to form alloys.  The magnesium nitride may be made by passing nitrogen through a heated mixture of a carbonaceous reducing agent and a magnesium compound such as magnesium oxide.
